Kayak A is initially at rest and then person B leaps off the kayak A with a relative velocity vB/A and lands in kayak C with person D. Each kayak has a mass of 40 kg, the mass of person B is 30 kg and the mass of person D is 25 kg. After person B leaves kayak A, the velocity of kayak A is 1.86 m/s to the left. After person B lands in kayak C the velocity of kayak C is 0.44 m/s to the right. Assuming the kayaks will not displace in the y direction, determine:.
